An older Lopi insert question

Hi folks!
This is such a helpful site! Nu-b and been lurking for about a week since I decided to supplement heating my home utilizing a fireplace insert. With limited finacial resources, I thought to buy a used one. Found this one on craigs but seller does not have model other than that it's a Lopi. I like the look of this model and would like to refinish (paint) the insert and panels and use if there are no "negative history" with this model. Can any of you id this model and provide any details for it? I have an 1800sf 1-story house with the masonry fireplace in the family room which is centrally located relative to the house. Will also check w/the county if there are any issues with this model once I have details.
Thanks for your input.

Correy,
Thanks for your response. Here is a picture of the unit w/out shroud. Can you figure out which unit it is? Have you heard of any negative issues with this model? Oh, the seller added: Lopi Fireplace Insert with Variable Speed Forced Air Fan Model LX, Serial Number 20511
Any additional info is greatly appreciated.

I was also just informed from the seller that it needs the internal "bricks". He is wanting $300. Now that I'll need the bricks is this worth it even if I could get him down to $200-250 range?

A little disappointed...
I just stopped at my local stove store and they told me that because I have one of the metal fireplaces put in a million track houses that it would be hard to fit a insert in the space opening (back 26" X depth 14" X height 16"). This unit I was looking at will not fit in that space either...ARGH!

Thanks. Yeh, that's been my luck so far. I've decided to now go with a free standing stove.
OH YEAH!
